Embodiment Construction

[0033] The following examples only illustrate possible embodiments of the present invention, which are not intended to limit the protection scope of the present invention, and are stated in advance.

[0034] Please refer to Figures 1 to 6 , which shows a preferred embodiment of the present invention, the tool set 1 with a replaceable driving head of the present invention includes a socket 10 , a jacket 20 and at least one limiting member 30 .

[0035] The connecting sleeve 10 is provided with an opposite accommodating groove 11 and a driving end 12. The inner wall of the accommodating groove 11 is provided with a plurality of axially extending convex ribs 13 and a plurality of grooves 14 between these convex ribs 13. In the radial section, each rib 13 has a convex arc 131 connected between two grooves 14 , in other words, both ends of each groove 14 are connected to two adjacent convex arcs 131 straightly or reversely. Furthermore, the extensions of any two adjacent convex a...

Abstract

The invention discloses a tool having a replaceable driving head and a set thereof. The set comprises a joint, a sheath and at least one limiting part. The joint is provided with an accommodating groove and a driving end, both of which are opposite to each other. Multiple protruding ribs extending axially and multiple grooves located among the protruding ribs are arranged on the inner wall of the accommodating groove. A groove of the accommodating groove is used for inserting connection of multi-angle spherical heads. The sheath can be connected outside the joint in the manner of mutually limiting an axial sliding sleeve group. The inner wall of the sheath is provided with a recess and a projection and can slide at the first position and the second position relative to the joint.Limiting parts are provided with protruding ribs which selectively protrude of the accommodating grooves.When the sheath is located at the first position, the projection abuts against the limiting parts and protrudes out of the accommodating grooves while the limiting parts are used for clamping and limiting the multi-angle spherical heads into the accommodating grooves. When the sheath is located at the second position, the recess is opposite to the limiting parts while the limiting parts can go in and out of the recess and the multi-angle spherical heads can be drawn out of the accommodating grooves.The tool having the replaceable driving head and the set thereof have following beneficial effects: the driving head can be rapidly replaced; the tool is simple in structure and convenient in manufacture and assembly; friction is decreased; and working efficiency is increased.

Description

technical field [0001] The invention relates to a tool with a replaceable driving head and its set. Background technique [0002] In the known two-stage joint, the polygonal spherical head of the support rod is accommodated in the accommodating groove of the working head, and the shape of the accommodating groove is polygonal corresponding to the polygonal spherical head, and the supporting structure is supported by a connecting structure. When the rod is pressed in, it can be fixed with the operation head, and when the support rod is pulled out, it can pivot relative to the operation head. What Taiwan Patent No. 566284 and M357344 disclose belongs to this category. [0003] In the structure disclosed in Taiwan Patent 566284, since the inner wall of the accommodating tank is polygonal, it is in surface-to-surface contact with the polygonal spherical head, and when an electric drive device is used to drive the support rod to rotate at a high speed relative to the operating h...
